Ah, so it seems to be a common problem, and might be solved
eventually.

On the other hand, for GNU/Linux systems, I wonder whether it isn't
easier to modify the kernel to run non-native binaries.  Similar to
how Windows binaries can be run like native binaries, through wine,
and the details are hidden by the system.  Instead of running wine,
you could use ssh to copy and log in on the remote machine.  This
won't solve the problem for proprietary platforms, but if someone
cares about that, they could sponsor a better solution... ;)
